Description
White to pale yellow Hygroscopic crystals. Sodium nitrite is used in dyeing textiles with developed dyes. It is also used as a Fixative for color photographs. In a closed environment, a saturated solution of sodium nitrite will form an equilibrium at a relative humidity of about 65% (20C).
Synonyms and Related Terms
nitrous acid sodium salt; erinitrit; nitrite
Risks
Carcinogenic in test animals. Strong oxidizing agent. Fire risk in contact with oxidizing materials. Used as an antidote for cyanide poisoning.
